To sum up: it looks like there's one utility IF spot to be won in ST, and one bullpen spot with three main competitors. For the bullpen, I give Septimo the edge because it balances the pen out at 3 lefties and 3 righties. The IF spot will probably be very much up for grabs, but Angel Sanchez probably has a head start on any competitors. I'm assuming Morel and Jordan Danks will both make the team, since Morel has put in his minor league time already, and Jordan Danks showed a lot of upside in his time with the team in 2012.
If Pierzynski comes back, catchers are set. If not, they will probably acquire a veteran to spell Flowers. I wouldn't mind seeing them go with either Miguel Olivo or Kelly Shoppach.

Danks and Morel -- esp. Morel since he can only play one position -- are far from sure things at this point.

Also, I'm almost positive we'll be going w/7 RP's instead of 6 from the start of the season, rather than waiting 2-3 weeks. Donnie Veal is pretty much guaranteed to make the team as a lefty specialist, and is held in higher regard by the organization than the Septimo/Omogrosso/Axelrod trio you mentioned.

That leaves four bench spots, of which Wise and the backup Catcher will take two. With the last two spots open, one needs to be filled with a true utility IF'er. The last spot can be a PH/OF/IF...doesn't really matter.

I'd like to see one veteran bat and arm traded for something young and significant for us to build into the lineup or the mound. I could, however, very well see us running out this squad and waiting out value and team performance for the deadline.

I think Jordan Danks will be in Charlotte though and the Sox will sign/acquire another veteran IF. Septimo is out of minor league options, and that always usually helps a player make the team out of ST, unless he straight up is disastrous.
